Vitamin A: Found in carrots, spinach, liver, eggs, and dairy
When following the OMAD diet, it is important to ensure adequate vitamin intake to support various bodily functions and prevent deficiencies. Vitamin A, in particular, is essential for maintaining healthy vision, immune function, bone remodelling, and reproductive health. This vitamin is available from both plant and animal sources.
Plant sources of vitamin A include vegetables such as carrots, spinach, kale, broccoli, sweet potatoes, and squash, as well as fruits like apricots, watermelon, mango, and guava. These plant-based foods contain beta-carotene, a precursor to vitamin A, which helps the eyes adjust in dim light and supports overall eye health. Beta-carotene is not toxic even at high levels of intake, so it is safe to consume these plant sources in moderate amounts.
Animal sources of vitamin A include liver, eggs, dairy, meat, fish, poultry, and oily fish. Liver, in particular, is one of the richest sources of vitamin A, as animals store vitamin A in their liver. A 3-ounce serving of pan-fried beef liver provides 6,582 micrograms of vitamin A, which is an exceptionally high amount. Other animal-based sources of vitamin A include cod liver oil, cheese, butter, and dairy products.
To enhance the absorption of vitamin A, it is recommended to include healthy fats in your OMAD meal, as vitamin A is fat-soluble. Avocado, olive oil, fatty fish like salmon, and other sources of healthy fats can improve the absorption of vitamin A from your diet. Additionally, if you are following a vegetarian or vegan diet, you may need to take supplements or consume a larger quantity of vitamin A-rich plant foods to ensure adequate intake.
While vitamin A is essential, it is important to be mindful of potential toxicity. Preformed vitamin A, or retinol, found in supplements and some animal-based sources, can become toxic if too much is stored in the body. Therefore, it is crucial to maintain a balanced intake and consult with a healthcare professional if you have any concerns about your vitamin A levels while on the OMAD diet.

Vitamin D: Sunlight on the skin is the best source, but supplements can help
Sunlight on the skin is the major source of vitamin D for our bodies. When the skin is exposed to sunlight, it makes vitamin D from cholesterol. Specifically, the sun's ultraviolet B (UVB) rays hit cholesterol in the skin cells, providing the energy for vitamin D synthesis. This process requires ultraviolet rays to form vitamin D3, which the liver and kidneys then convert into the active form of vitamin D.
However, those with inadequate sun exposure, including disabled people, infants, the elderly, dark-skinned people, and those who live at northern latitudes during the winter, are at risk of low vitamin D3 production. This can lead to a loss of bone density and an increased risk of fractures. People with darker skin have more melanin, so less UV light gets absorbed to create vitamin D3. They need more sun exposure to produce vitamin D3 than those with lighter skin.
To address this issue, it is recommended to expose around a third of the skin's surface area to sunlight. The British Skin Foundation recommends daily sunlight exposure of 10-15 minutes for lighter skin and 25-40 minutes for darker skin. In the spring and summer, exposing 25% of the body (hands, face, neck, and arms) to the sun for 8-10 minutes at noon can produce sufficient vitamin D. In the winter, exposing 10% of the body for nearly 2 hours at noon is recommended.
While sunlight is the best source of vitamin D, supplements can also help. Vitamin D supplements are often recommended for those who do not get enough sunlight. Additionally, vitamin D can be obtained from a handful of foods, including cod liver oil, swordfish, salmon, canned tuna, beef liver, egg yolks, and sardines. However, these foods would need to be consumed nearly every day to provide sufficient vitamin D.
When following the OMAD (One Meal a Day) diet, it is crucial to ensure a balanced intake of essential vitamins, minerals, fatty acids, and protein. While sunlight is the best source of vitamin D, those on the OMAD diet may consider taking vitamin D supplements to meet their requirements, especially if they are not exposed to sufficient sunlight.

Electrolytes: Magnesium, calcium, potassium, and chloride are vital for nerve function and muscle contractions
When following the OMAD diet, it is important to ensure that you are getting a balanced intake of essential vitamins and minerals. This is crucial to support various cellular functions and prevent deficiencies. One key area to focus on is electrolytes, specifically magnesium, calcium, potassium, and chloride, which are vital for nerve function and muscle contractions.
Magnesium, calcium, potassium, and chloride are all essential for maintaining proper nerve function and muscle contractions. These electrolytes work together to regulate nerve impulses and facilitate muscle contractions and relaxation. Potassium plays a crucial role in maintaining the electrical gradient across muscle cell membranes, which is necessary for nerve impulse transmission. Calcium ions, on the other hand, bind to troponin during muscle contraction, causing a conformational change that allows for the interaction of actin and myosin filaments, resulting in muscle shortening. Additionally, calcium is involved in the transmission of nerve impulses and plays a role in skeletal mineralization, blood clotting, and hormone secretion. Magnesium is involved in adenine triphosphate (ATP) metabolism, proper muscle function, neurological functioning, and neurotransmitter release. It is important to note that alcohol use disorder, gastrointestinal conditions, and excessive renal loss may lead to hypomagnesemia, which can have serious health consequences.
Maintaining proper electrolyte balance is crucial for overall health and well-being. Electrolytes are essential for basic life functions, such as maintaining electrical neutrality in cells and generating nerve impulses and muscle contractions. An imbalance in electrolytes can lead to high or low levels, disrupting normal bodily functions and potentially resulting in life-threatening complications. Therefore, it is important to monitor your intake of electrolytes and ensure proper hydration to avoid overconsumption or deficiencies that can lead to decreased performance, slower reaction times, increased fatigue, and muscle cramps.
To maintain proper electrolyte balance while on the OMAD diet, incorporate foods rich in these minerals into your daily meal. Potassium can be found in bananas, potatoes, and leafy greens. Dairy products and nuts are good sources of calcium. Avocados are a great source of magnesium, and sea vegetables can provide both sodium and chloride. Additionally, consider electrolyte supplements, especially if you are physically active and losing electrolytes through sweat.
In summary, when following the OMAD diet, it is important to focus on essential electrolytes like magnesium, calcium, potassium, and chloride. These minerals play vital roles in nerve function and muscle contractions, and proper intake can help prevent deficiencies, maintain muscle health, and support overall health and well-being.

Minerals: Iodine and zinc are important for thyroid function and immune health
Minerals play a crucial role in maintaining optimal health, and two essential minerals that deserve special attention are iodine and zinc.
Iodine is a vital mineral that supports thyroid function and immune health. It assists in the conversion of thyroid-stimulating hormones (TSH) into triiodothyronine (T3) and thyroxine (T4), which are essential for the thyroid to function properly. Iodine also acts as an antioxidant, helping to reduce tissue damage and oxidative stress caused by free radicals. This, in turn, supports immune function and helps prevent chronic diseases. Iodine is particularly important for breast health and has been shown to effectively address cyclic mastalgia associated with fibrocystic breast disease. Additionally, iodine's ability to function as an oxidant through its antimicrobial properties further enhances its role in immune support.
Zinc is another essential mineral that plays a significant role in thyroid and immune health. It is involved in activating thyroid hormones, ensuring they are biologically active and functional. Zinc is also critical for the development and function of immune cells, influencing health from early life into old age. Zinc deficiency during pregnancy has been linked to abnormalities in embryo development and poor health in newborns. Adequate zinc intake is necessary for the regular development of oocytes and the completion of meiosis. Furthermore, zinc's role as a gatekeeper of immune function is evident in its involvement with regulating intracellular signaling pathways in innate and adaptive immune cells.
To ensure adequate intake of iodine, include foods such as dried seaweed, wild-caught cod, plain yogurt, iodized salt, wild-caught shrimp, pastured eggs, and tuna in your diet. For zinc, focus on consuming oysters, grass-fed beef, chicken, Alaskan king crab, pork chops, shiitake mushrooms, lentils, and plain yogurt.
By incorporating these iodine and zinc-rich foods into your diet, you can support the optimal functioning of your thyroid and bolster your immune health.
